10.2.9 NCK utilization
Introduction
You can view utilization of system resources for the NCK on the HMI under the menu
"Diagnostics > Service displays > System resources".
Figure 10-2 NC utilization
The following machine data is taken into consideration for displayed runtimes (see Chapter
Cycle times (Page 108) ):
• MD1061 POSCTRL_CYCLE_TIME = MD10050 SYSCLOCK_CYCLE_TIME (System
basic cycle)
• MD1070 IPO_SYSCLOCK_TIME_RATIO (factor for interpolation cycle)
• MD1071 IPO_CYCLE_TIME (interpolation cycle)
What will be displayed?
In the display of the "System resources" menu, the values have the following meaning:
• Area "Nett runtime (purely CPU time)":
Active times (current, minimum and maximum) are displayed in the nett values.
The relation to the machine data can be seen from the displayed values.
• Area "Gross runtime (time from start to end)":
The corresponding total utilization of the system (position controller + interpolator) is
displayed, based on the net values.
• Line "NCU load by position controller and interpolator":
